[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] In the description of the present invention, it should be understood that the terms "opening", "upper", "middle", "length", "inner" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0034] Example 1: Please refer to Figure 1-5 As shown, in this embodiment, a packaging box is provided, which includes an upper box body 1, a lower box body 2, a movable cover 9, a movable inner cover 11 and a pull-out box 3.

[0035] First, the upper box 1 is used to store and package items. The lower box 2 is fixedly mounted on the bottom of the upper box 1. Its main function is to thicken and protect the bottom of the upper box 1, thereby improving the overall load-bearing capacity and leak-proof performance of the entire packaging box. The lower box 2 and the upper box 1 can be connected using glue, staplers, or other fixing methods to ensure a secure connection.

[0036] A movable lid 9 is hinged to the top of the upper box body 1 and is used to close or open the opening of the upper box body 1. A locking tab 10 is hinged to one side of the movable lid 9. This tab 10 can be bent around the hinge point to engage with a slot in the upper box body 1, securing the movable lid 9. This design allows the movable lid 9 to close the opening of the upper box body 1, preventing items inside from falling or being contaminated by the outside world.

[0037] The two movable inner covers 11 are hinged to the inner walls on both sides of the upper box body 1 and are both located at the opening of the upper box body 1. The two movable inner covers 11 form a card slot with one side of the upper box body 1, which cooperates with the card piece 10 to further enhance the sealing performance of the packaging box.

[0038] The lower box body 2 is provided with a through slot, through which a pull-out box 3 is slidably arranged. The pull-out box 3 is used to store additional items, making it convenient for users to store and access them in a classified manner. The pull-out box 3 can slide freely within the lower box body 2, improving the convenience of use.

[0039] In addition, a plurality of communication holes 4 are provided on the top of the lower box body 2, which pass through the bottom of the upper box body 1 and are staggered with the ridges 5. The communication holes 4 allow the upper box body 1 to communicate with the pull-out box 3, thereby improving the functionality of the packaging box.

[0040] To secure the drawer 3 in place, connecting strips 7 are attached to both sides of the upper body 1. The bottom of the connecting strips 7 extends to one side of the lower body 2 and is attached to both the lower body 2 and the drawer 3. This design prevents the drawer 3 from slipping out of the lower body 2 when the package is not in use, improving the safety and stability of the package.

[0041] In order to facilitate the user to tear off the connecting strip 7, a plurality of grooves 8 are provided on one side of the connecting strip 7 close to the upper box body 1. These grooves 8 reduce the contact area between the connecting strip 7 and the upper box body 1, the lower box body 2, and the pull-out box 3, thereby reducing the resistance when tearing off.

[0042] In order to increase the friction when the user picks up the packaging box, the outer walls of the two connecting strips 7 are provided with continuous protrusions. These protrusions increase the contact area and friction between the user's fingers and the connecting strips 7, allowing the user to pick up the packaging box more easily.

[0043] The present application can be used in the technical field of packaging boxes, and can also be used in other fields applicable to the present application.

[0044] Example 2: Reference Figure 2 、 3 5. Improvement based on Example 1: A bottom leak-proof packaging box, which is applied to the field of packaging box technology;

[0045] To further enhance the upper box body's load-bearing capacity and resistance to deformation, a support frame 6 is slidably mounted within the upper box body 1. This support frame 6 consists of two reinforcement frames 13 and a connecting piece 14, which is fixedly mounted between the two reinforcement frames 13. The reinforcement frame 13 is composed of four L-shaped reinforcement plates 15 and four connecting plates 16, which are fixedly connected in sequence to form a rectangular frame. The L-shaped reinforcement plates 15 reinforce the corners of the upper box body 1, effectively preventing distortion.

[0046] In order to facilitate the opening of the movable cover 9, an arc groove 12 is provided on the top of the upper box body 1. The arc groove 12 cooperates with the locking piece 10, and the user can insert a finger into the arc groove 12 and push the locking piece 10 to easily open the movable cover 9.

[0047] To increase the sliding friction between the pull-out box 3 and the inner wall of the lower box body 2 and prevent the pull-out box 3 from sliding when not under external force, a plurality of ridges 5 are fixedly mounted on the top inner wall of the lower box body 2. These ridges 5 contact the bottom of the pull-out box 3, increasing the friction between the two. This ensures that the pull-out box can remain stably placed inside the lower box body even after the connecting strip is removed, facilitating repeated use of the pull-out box and extending the service life of the packaging box.

[0048] The use process and working principle of the technical solution of this utility model are as follows:

[0049] When in use, the user can use the arc groove 12 to push the locking piece 10 on one side of the movable cover 9 until the locking piece 10 disengages from the locking groove formed by the two movable inner covers 11 and one side of the upper box body 1. At this time, the movable cover 9 can be opened, which is convenient for the user to take out the items stored in the upper box body 1; in addition to the items to be placed, the interior of the upper box body 1 is also provided with a support frame 6, which can provide support for the upper box body 1 from the inside of the upper box body 1; when the user needs to take out the support frame 6, he only needs to ensure that the movable cover 9 and the two movable inner covers 11 are fully opened, and then slide the support frame 6 out of the upper box body 1; the upper box body 1 can strengthen the bottom of the upper box body 1 by providing the lower box body 2 at the bottom, avoiding the phenomenon that the bottom support bearing capacity of traditional packaging boxes is poor and items are easy to leak and fall off; the interior of the lower box body 2 is also provided with a pull-out box 3, which can be used to store additional items, such as instructions, When the drawer 3 is opened, the drawer 3 is opened, and the drawer 3 is opened, and the drawer 3 is opened, and the drawer 3 is opened, and the drawer 3 is opened, and the drawer 3 is opened, and the drawer 3 is opened.
